Nov.14 (GMM) Bernie Ecclestone's wife has moved out of their Kensington (UK) home, reports on Friday said.

British newspapers including the Evening Standard and the Daily Mail claim the F1 chief executive could be facing a multi-billion dollar divorce, after Slavica Ecclestone moved into a flat overlooking the Thames owned by their daughter Petra.

Their split and divorce could be extremely complicated, given that it is believed most of 78-year-old Ecclestone's estimated $3.5 billion fortune is in his non-domiciled wife's name, for tax reasons.

The newspapers said Slavica, who is 28 years younger than Bernie and ten inches taller, moved out of their house while Ecclestone was in Brazil for the 2008 season finale.

The Evening Standard said Slavica has consulted with divorce lawyers. It is believed Bernie would have to sue his wife to retrieve his fortune.

"I don't want to say anything. You can talk to my husband," she said.

Bernie insists she moved out because of the noise of renovation work in the house next door.

He said: "She can't stand the noise. I don't know if she wants a divorce or not."
